External compression of a vein is a relatively rare but important cause of unilateral leg edema. Here, we present a case of unilateral right leg edema caused by external compression of the right iliac vein due to a markedly distended urinary bladder, secondary to a neurogenic bladder. The patient initially had bilateral leg edema associated with chronic heart failure. However, the right-leg edema worsened and remained painful for several days. Lower extremity ultrasonography and computed tomography revealed an enlarged bladder. Based on these findings, venous angiography and intravascular ultrasound were performed. External compression is a significant cause of leg edema. It is important to consider the possibility of intra-abdominal/pelvic processes that may lead to external compression of the venous system in patients with unilateral and even bilateral lower extremity swelling.
静脉外部受压是单侧腿部水肿相对罕见但重要的原因。在此，我们报告一例因神经源性膀胱继发的膀胱明显扩张导致右髂静脉外部受压引起的单侧右腿水肿病例。患者最初因慢性心力衰竭出现双侧腿部水肿。然而，右腿水肿加重并持续疼痛数天。下肢超声和计算机断层扫描显示膀胱增大。基于这些发现，进行了静脉血管造影和血管内超声检查。外部受压是腿部水肿的一个重要原因。对于单侧甚至双侧下肢肿胀的患者，考虑可能导致静脉系统外部受压的腹内/盆腔病变的可能性很重要。
